You are locked in

There are quite a lot of bugs given the price. The development seems to be a little too fast. The problem is that the support cannot help you. I have an error which the support now finally accepts but cannot provide ETA on. A rather important one: Registered users cannot be upgraded by forms to affiliates meaning they cannot register themselves. You have to do it. And another where the admin area throws an exception.

It seems easy, but you are locked in, so be sure to make the right choice.
